Mathematics Hiding in the Nets for a Cube
Jeon, Kyungsoon
Teaching Children Mathematics, v15 n7 p394-399 Mar 2009
Whether they are third graders or teacher candidates, students can learn about perimeter and area while having fun manipulating two-dimensional figures into three-dimensional objects. In this article, the author describes a common mathematical activity for geometry students by creating nets for a cube. By making connections between nets in two dimensions and cubes in three dimensions, the author explains why the nets have the same area and, more interesting, the same perimeter. The author also makes connections to other platonic solids and to Euler's formula. (Contains 7 figures.)
